Maytag Stack Laundry Washer & Dryer SE 1000 SG 1000

Always disconnect power supply before making any continuity checks or resistance readings.

The amperage readings are at 240 volts. One line will be 24 amps and the other line will be 21 amps. The neutral line will be at 4 amps. If you have the above amperage readings, the problem is not the dryer. Check the fuse box, circuit breaker or house wiring.

� During ignition the dryer will draw 7 amps. With the burner on, the dryer will draw 4.5 amps. If the dryer is drawing the above amperage and the fuse blows, the problem is not the dryer. Check the fuse box, circuit breaker or house wiring.

Always disconnect power supply before making any continuity checks or resistance readings.

Will Not Dry
Dryer won't heat (motor runs).

ELECTRIC MODELS

� Blown fuse or tripped circuit breaker.
� Open heating element.
� Hi-limit thermostat.
� Regulating thermostat. Temperature selector switch.
� Timer.
� Cycle selector switch (where used).
� Drive motor start switch.

Improper Drying -- Clothes Wrinkled --

Harsh -- Taking too long Lint filter is clean. Restriction in exhaust. Exhaust hood door stuck. Exhaust too long. Poor make-up air. Incorrect drum speed. Adjust motor pulley or wrong motor pulley.

� Blower impeller bound.
� Be sure element or gas valve cycles on and off.
� Shorted heating element - electric dryers only.
� Customer overloading dryer. Check clothing labels for fabric content.

MISCELLANEOUS

Dryer noisy.

� Thumping sound. Check for loose drum baffle.
� Thumping sound. Rear drum roller(s) worn or misaligned.
Thumping sound. Check drum for rough spots.
� Ticking sound. Loose wire hitting cabinet or other component.
Ticking sound. Check for a n object caught in the blower.

Scraping sound, Front or rear bulkhead felt seal out of position.

� Scraping sound. Teflon bearings mounted to the front bulkhead worn.
� Popping or squealing sound. Check for a sticky belt or frayed belt.

Buzzer will not buzz at end of cycle.
� Be sure all wires are connected and wired correctly on the timer, buzzer and drive motor.
� Buzzer.
� Motor centrifugal switch sticking in run position.

Buzzer stays on too long or goes off too quickly.

Length of time the buzzer stays on is dependent upon the time it takes the motor to slow down, allowing the motor switch to reset. The normal time increment is between 2 and 3 seconds.

Buzzer will not periodically buzz during permanent press cool down.

* Timer.

FAULT CODE

The microprocessor board has the capability to detect certain problems associated with the operation of the dryer. When the microprocessor board detects one of these problems it displays a fault code in the dryer's display window. The fault code is displayed as a letter E followed by a number that corresponds to the problem.

FAULT CODES

* 9E corresponds to a malfunction in the
dryer door circuit on the control board.

8E Corresponds to a malfunction in the motor relay circuit.

7E corresponds to a temperature control error in which either the thermistor circuit is in error or the 150 degree thermostat circuit has failed and the dryer has reached an abnormal temperature.

6E corresponds to another temperature control error in which either the thermistor circuit is in error or the temperature surrounding the dryer is too low for proper operation.

Always disconnect power supply before making any continuity checks or resistance readings.

DIRECT IGNITION SYSTEM

- CAUTION

Always disconnect power supply before making continuity or resistance checks.

When the dryer is operated on a heat setting, the ignitor should be energized and the burner shall fire within 45 seconds at 120 volts. Check for the existence of the flame. De-energize the gas control and re-energize. The flame should reappear within one minute.

The failure of a component in this system will usually be indicated by one of three symptoms:

1. The ignitor does not glow.

2. The ignitor glows but no gas ignition takes place.

3. The gas is ignited but the flame goes out.

1. No Ignitor Glow

If the ignitor does not heat up, remove power and using an ohmmeter, check the following:
� Open Flame Sensor
� Open Ignitor
� Shorted Booster Coil
� Open Wiring

2. Ignitor Glows - No Gas Ignition

If the ignitor heats up but the main burner flame is not ignited, remove power and using an ohmmeter, check the following:
� Open Secondary Coil
� Open Holding Coil
� Open Wire

Other causes that will not show up in a continuity check but should be examined:
� Check Gas Valve
� Restriction in the Burner Orifice
� Ignitor Improperly Installed

Gas Ignites - Flame Goes Out

If a normal ignition takes place and after a short while the flame goes out, check for the following:
� Erratic Radiant Sensor
� Coils on Gas Valve

CAUTION

Reconnect electrical wires and check all gas connections for leaks before reconnecting to power supply.
